Question about tmux TERM #41

Closed ethagnawl closed 1 year ago

ethagnawl commented 1 year ago

Thanks for this versatile plugin! I can confirm that it's working great when sshing into my remote server and is a tremendous productivity booster.

Unfortunately, I'm getting hung up trying to use it in conjunction with tmux on the remote server. I think my problem is that I'm unable to set Ms correctly via the various tmux configuration incantations. I've tried upgrading from 2.6 to 3.4-next and that didn't change anything. Something that I'm not entirely clear on, which is probably the problem, is that I'm not sure which machine's $TERM I should be using: my host or the server? I'm also not clear on whether tmux is expected to be running on the local machine or on the server in the linked documentation. (To be clear: I'm trying to ssh into a remote machine, run tmux on the remote machine and run vim inside the remote tmux session.)

Any pointers would be greatly appreciated!

Hello, I'm glad you like the plugin.

To work with tmux, you need two things:

Your terminal emulator must be compatible with OSC52 but that seems to be the case.
On machine where you have your tmux instance running, so on the remote machine in your case, you need to put this in your tmux config: set -s set-clipboard on (and not external).

That should be all for the plugin to work.

Thanks for the prompt response, @ojroques!

I have tried adding both set-clipboard on|external to my tmux config without success. I'm going to try again with a simplified tmux config, though.

ojroques commented 1 year ago

Could you share your vim and tmux config on the remote server ? Also, what terminal emulator are you using ?

ethagnawl commented 1 year ago

I just rebuilt tmux next-3.4 and it's now working using: set-option -s set-clipboard on. I'm not sure what changed but I'll follow up if I can figure it out.

Either way, thanks for your help and for such a useful utility!

I did just uncover something strange. As mentioned, I built tmux myself and when I start it using $PATH Ms is not set; when I start it using the absolute path to the same binary, Ms does get set and this plugin works as expected. This is almost certainly not a vim-oscyank issue but I wanted to mention it in case anyone else runs into this particular problem.

Good to know, thanks.
